Cathode protection of Underground pipelines in petrochemical Antiexplosive plant Site

摘要

This paper gave a brief account of the application of cathodic protection in underground pipelines within liao HUa antiexplosive plant site. The technical restricted zone was broken through that there is no cathodic protection without insulated flanges. The safety of antiexplosive plant site by cathodic protection was realized and the side-effect was avoided. Application of cathodic protection has been introduced to petrochemical fields. This technique creates huge economic benefits for Liao Hua Company.
